Abstract: A rotating mechanism for a cosmetic case includes a slider (2) that is equipped with two studs, each of which crosses a helicoidal opening (6) of a spiral casing (3) that is pressed onto the slider (2). The studs each extend into a longitudinal port that is arranged inside an exterior sleeve (4) and that is pressed onto the spiral casing (3). The slider (2) includes two parts, namely an upper end including a cradle (13) designed to receive a cosmetic product, and an elongated cylindrical portion (14) in which the studs at its lower end are arranged.

Abstract: A rotating cosmetic case including an outer metal jacket (1) fitted and mechanically retained to a sheath of synthetic material, at the same time by at least one rotational lock and at least one tensile lock. A rotational lock may include a cut-out (5) opening outwards at the lower end of the cylindrical wall of the metal jacket (1), this cut-out (5) being mounted in conjunction with a molded projection in the sheath, while the tensile lock may include at least one aperture (7) in the lower part of the cylindrical wall of the metal sheath (1) defining, with the lower end of the sheath (1), a wall portion (8) directed inwards with respect to a housing located in the sheath.

Abstract: A rotating cosmetics case intended to receive a cosmetics product, such as a stick of lipstick or lip cream, comprising a metal jacket (5) fitted on a sheath of synthetic material, while the metal jacket (5) and the sheath of synthetic material are held mechanically in a form-fitting manner, that is, one of the parts comprises at least one protruding profile, while the other comprises at least one recessed profile, the recessed and protruding profiles being arranged correspondingly.

Abstract: Installation for surface treatment of parts. The installation includes at least one treatment tank containing a processing liquid in which an arm carrying on one of its ends at least one part support comprising a lower surface and an upper surface holding the parts to be treated is at least partially immersed. The arm is rotationally mounted about an axis located on the outside of the tank and in an area below the area formed by the upper end edge of the tank.

Abstract: The invention relates to an equipment for the surface treatment of parts (4), that comprises a plurality of treatment vats arranged in series and comprising rotating drums (2) provided with means for temporarily attaching the parts to be processed and having their axes (XX?) rotatingly mounted horizontally so that the major portion of each drum (2) is submerged in the processing liquid contained in the corresponding vat, and a conveyor line (14) for supplying each drum (2) with parts to be processed and for removing from said drum the parts already processed, characterized in that the conveying process is carried out along a general axis (ZZ?), and in that the axes (XX?) of the drums are parallel relative to each other and parallel to the general axis (ZZ?) of the conveyor line.

Abstract: The invention relates to a machine for the surface processing of metal parts by immersion into at least one processing liquid contained in a processing tank comprising a plurality of tanks arranged in series and to a device for transferring the parts between the tanks, said tanks each including a rotary structure mounted on a rotation axis for receiving said parts submerged by a rotation movement of the rotary structures such that the air bubbles generated by the immersion of the parts are chased from the surfaces thereof, machine in which said rotation axis are rotatingly rigidly connected and driven by a common driving device. The tanks arranged in series may be contiguous and the rotation axes of the rotary structures may be aligned and assembled so as to form a common rotation axis extending through the entire machine.
